For Pacific white shrimp, gender matters when competing for food
12-12-2006 · EurekAlert!A new study in Journal of the World Aquaculture Society suggests that, while larger shrimp consistently win over smaller shrimp of the same gender when competing for food, male shrimp will almost always beat female shrimp -- even though adult males of the species are typically much smaller than the adult females of the same age.

- Nanotechnology's future depends on who the public trusts
02-15-2008 · EurekAlert!
When the public considers competing arguments about a new technology's potential risks and benefits, people will tend to agree with the expert whose values are closest to their own, no matter what position the expert takes. The same will hold true for nanotechnology, a key study has found.

- Pedophilia may be the result of faulty brain wiring
11-28-2007 · EurekAlert!
Pedophilia might be the result of faulty connections in the brain. A new study from CAMH showed that pedophiles had significantly less "white matter." The study challenges the commonly held belief that pedophilia is brought on by childhood trauma or abuse. This finding is the strongest evidence yet that pedophilia is instead the result of a problem in brain development.

- Humboldt squid on the move
07-25-2007 · EurekAlert!
Over the last five years, large, predatory Humboldt squid have moved north from equatorial waters and invaded the sea off Central California, where they may be decimating populations of Pacific hake, an important commercial fish. Ironically, these squid may have benefited from the decline of large tuna and billfish in the Equatorial Pacific. Historically, such large commercial fish preyed on and competed with the Humboldt squid for food.

- Emphasis on conifer forests places multiple species at risk
08-23-2007 · EurekAlert!
The traditional emphasis on dense, fast-growing, conifer-dominated forests in the Pacific Northwest raises questions about the health of dozens of animal species that depend on shrubs, herbs and broad-leaf trees. At least 78 vertebrate species have been documented that require, in one way or another, the food or habitat provided by non-coniferous vegetation, and may be at increasing risk.

- Old food meets new technologies, leaves food for thought
02-16-2007 · EurekAlert!
There are big changes driven by small forces in two of the oldest industries of the US economy -- agriculture and agricultural production.From the fields to the grocery store shelves, nanotechnology -- technology that allows the control of unique, sub-molecular properties of matter -- is revolutionizing the way food is produced, packaged and distributed, leaving many in the industry grappling with nanotechnology's numerous implications.

05-01-2007 · EurekAlert!
Eating disorders may be overlooked in some groups -- boys and some ethnicities -- by physicians accustomed to diagnosing the condition in white teenage girls, say researchers at Lucile Packard Children's Hospital and the Stanford University School of Medicine.

- Carnegie Mellon uses new imaging technique to discover differences in brains of people with autism
10-23-2006 · EurekAlert!
Using a new form of brain imaging known as diffusion tensor imaging (DTI), researchers in the Center for Cognitive Brain Imaging at Carnegie Mellon University have discovered that the so-called white matter in the brains of people with autism has lower structural integrity than in the brains of normal individuals. This provides further evidence that the anatomical differences characterizing the brains of people with autism are related to the way those brains process information.

- Children's scientists discover fundamental protein instrumental to brain development and repair
07-08-2007 · EurekAlert!
Scientists at Children's National Medical Center have demonstrated conclusively that a specific protein and its signaling activity are instrumental in myelination and remyelination, processes essential to the creation and repair of the brain's white matter. This groundbreaking discovery in mouse models points the way to developing treatments to enhance healthy brain development and/or brain disease repair in children and adults.
